Example Question #239 : Ssat Elementary Level Reading Comprehension

Adapted from "Life Growth - Frogs" by Margaret Warner Morley in A Book of Natural History (1902, ed. David Starr Jordan)

Our common frogs, like many of the fishes, do not trouble themselves about the fate of their eggs after they are carefully laid in a safe place. They trust Mother Nature to see the little tadpoles safely through the perils of childhood, to help them avoid being eaten or starving, and cut, not their teeth, but their arms and legs.

In Venezuela, however, there dwells a frog with well developed maternal instinct. The mothers have pockets on their backs, not for their own convenience, but as cradles for their babies. The fathers put the fertilized eggs into the pockets of the mothers, and there they remain, well guarded, until the young are able to care for themselves.

Which of these inferences does the wording of the passage demonstrate to be false?

Possible Answers:

Maternal instincts are uncommon among animals.

Fishes and frogs have a great deal in common.

The author is from Venezuela.

There are fewer types of frogs in Venezuela than in America.

The author has studied the behavior of many types of animals.

Correct answer:

The author is from Venezuela.

Explanation:

The inference that is least likely to be true is that “the author is from Venezuela.” You know this is highly unlikely to be true because the author says “Our common frogs . . . “ when talking about the frogs outside Venezuela. The use of the word “our” suggests she is part of the community from which these non-Venezuelan frogs are also from. We cannot reasonably infer any of the answers to be untrue. You might be tempted to answer “Maternal instincts are uncommon among animals,” but seeing as the author only talks about the instincts of frogs and fishes, there are few concrete conclusions that can be drawn.

Example Question #81 : Science Passages

Adapted from Anecdotes of the Habits and Instincts of Animals by Mrs. R. Lee (1852)

The Carnivora are divided by naturalists into three groups, the characters of which are taken from their feet and manner of walking. Bears rank among the Plantigrada, or those which put the whole of their feet firmly upon the ground when they walk. They are occasionally cunning and ferocious, but often evince good humor and a great love of fun. In their wild state, they are solitary the greater part of their lives. They climb trees with great facility; live in caverns, holes, and hollow trees; and in cold countries, retire to some sequestered spot during the winter, where they remain concealed and bring forth their young. Some say they are torpid, but this cannot be, for the female bears come from their retreats with cubs that have lived upon them, and it is not likely that they can have reared them and remained without food; they are, however, often very lean and wasted, and the absorption of their generally large portion of fat contributes to their nourishment. The story that they live by sucking their paws is, as may be supposed, a fable; when well-fed they always lick their paws, very often accompanying the action with a peculiar sort of mumbling noise. There are a few which will never eat flesh, and all are able to do without it. They are, generally speaking, large, clumsy, and awkward, possessing large claws for digging, and often walk on their hind feet, a facility afforded them by the peculiar formation of their thigh bone. They do not often attack in the first instance, unless impelled by hunger or danger; they are, however, formidable opponents when excited. In former times, there were few parts of the globe in which they were not to be found, but, like other wild animals, they have disappeared before the advance of man. Still they are found in certain spots from the northern regions of the world to the burning climes of Africa, Asia, and America. The latest date of their appearance in Great Britain was in Scotland during the year 1057.

The author of this passage would most likely believe that someone who had been attacked by a bear was __________.

Possible Answers:

Extremely foolish to have gotten himself in that position

Very unlucky to have caught a bear at the wrong moment

Responsible for the well-being of the bear

Foolish or unlucky depending on the circumstances surrounding the attack

It is impossible to say.

Correct answer:

Foolish or unlucky depending on the circumstances surrounding the attack

Explanation:

Answering this question requires you to read the passage carefully and select the relevant piece of information from which to make a prediction. Toward the end of the passage, the author says, “[Bears] do not often attack in the first instance, unless impelled by hunger or danger; they are, however, formidable opponents when excited.” So, in the author's opinion, bears only attack when forced by “hunger or danger"; from this, we can reasonably predict that the author of this passage would believe someone attacked by a bear would have been either foolish or unlucky—foolish if he or she made the bear feel in danger, unlucky if he or she encountered the bear when it was hungry.
